Frankincense is the air-dried gum resin of the frankincense tree. The small lumps of resin take on a colour between brown, reddish or white-yellow, depending on the time of harvest. Frankincense and its raw material myrrh have been well known since ancient times. Even today, frankincense is associated with the scent of the burnt plant for religious purposes. Frankincense is also consumed for various purposes.
